From b5210e5963a419cfd0aa59946802b181017929d6 Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Mon, 28 Jul 2025 22:45:09 +0200 Subject: [PATCH] feat: add comprehensive performance benchmark tracking system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Create benchmark test suites for critical operations: - Node loading performance - Database query performance - Search operations performance - Validation performance - MCP tool execution performance - Add GitHub Actions workflow for benchmark tracking: - Runs on push to main and PRs - Uses github-action-benchmark for historical tracking - Comments on PRs with performance results - Alerts on >10% performance regressions - Stores results in GitHub Pages - Create benchmark infrastructure: - Custom Vitest benchmark configuration - JSON reporter for CI results - Result formatter for github-action-benchmark - Performance threshold documentation - Add supporting utilities: - SQLiteStorageService for benchmark database setup - MCPEngine wrapper for testing MCP tools - Test factories for generating benchmark data - Enhanced NodeRepository with benchmark methods - Document benchmark system: - Comprehensive benchmark guide in docs/BENCHMARKS.md - Performance thresholds in .github/BENCHMARK_THRESHOLDS.md - README for benchmarks directory - Integration with existing test suite The benchmark system will help monitor performance over time and catch regressions before they reach production. ๐Ÿค– Generated with [Claude
